The main reasons why students should not have cell phones in school are: carrying cell phone in school enables students to cheat easily during their examinations. Using a cell phone in school can also distract them from their studies and also their classmates as well. Students who carry cell phone are highly exposed to pornographic materials and violent music which can easily influence them and affect their studies.
I'm not giving 3 reasons, just one, it's school, not Angry Bird and texting time, I'm not sure if I'm the only one that remembers this, but there was a time, like 15 years ago, I'm not talking about the 40's, when there were no cell phones, and somehow we all found a way to survive without constantly being in contact with one another, we either hung out, or called friends when we got home, we weren't texting our buddy sitting in the chair next to us while the teacher was up there teaching.
I don't get this need to have cellphones in school ... they are distracting in the classroom, emit radiation to your body and drain your body of energy. If you have to have them, turn them off and put them in your bag and turn on at the end of school if you need to. They are becoming an 'addiction' for people these days.
Reason 1)They become to focused on their phone resulting in being distracted for what they are there for. Reason 2) the school becomes involved with the devices, meaning: who is responsible when it becomes lost or stolen or tampered with, especially once it's been confiscated. Reason 3) students are at school to also learn social skills. A cell phone is an easy way to disengage, otherwise why not be homeschooled or be in an online hs program. Schools go back and forth on this issue. Some schools address this issue better then others.
